SIG Sauer P365 Nitron Micro-Compact 9 mm 3.1-Inch 10+1 Striker-Fired Pistol
The P365 changed the concealed-carry market, and this Nitron Micro-Compact example delivers that benchmark capacity in a slim, ultra-concealable package. Rated for +P ammunition and built around SIG’s serialized fire-control unit, it blends a matte-black Nitron-finished slide with XRAY3 night sights and a crisp striker-fired trigger—offering reliable performance in a footprint that still holds 10+1 rounds.

The micro-size P365 introduced a patented modified double-stack magazine that allows a full 10-round capacity without increasing grip width. This example ships with two factory mags so you can carry with a spare ready.
The 3.1-inch carbon-steel barrel is nitride treated for corrosion resistance and durability, while the stainless-steel slide wears SIG’s matte-black Nitron finish with front and rear cocking serrations for confident manipulation.
Factory fixed SIG XRAY3 tritium sights provide a bright green front outline and two-dot rear for fast, low-light target acquisition. The 4.9-inch sight radius helps maximize practical accuracy from the micro-compact frame.
A micro SIG rail accepts compatible lights or lasers, and the polymer grip module features molded stippling for secure control. The curved trigger delivers a consistent striker-fired break, and the pistol is rated for +P 9 mm ammunition for defensive loads.
